I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
When a fish swims from salt water into fresh water its cells react by losing water and shrinking. The correct option is D.
<h3>What is fresh water?</h3>
Glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands, and even groundwater contain fresh water.
These freshwater habitats cover less than 1% of the world's total surface area but are home to 10% of all known animals and up to 40% of all known fish species.
When a fish swims from salt water into fresh water its cells react by losing water and shrinking due to osmosis.
Thus, the correct option is D.

A hydrogen bond connects the nitrogenous bases of the nucleotides together!
D. DNA
All organisms contain dna
The reasons are many. The most major reason was the fact that they were outnumbered by the U.S.
